It is therefore evident that the sea superiority of Holland detracted greatly from Sweden's value as an ally to Louis XIV.
Another maritime strife arose in the Mediterranean by the revolt of the Sicilians against the Spanish rule.[59] The help they asked from France was granted as a diversion against Spain, but the Sicilian enterprise never became more than a side issue.

Its naval interest springs from bringing Ruyter once more on the scene, and that as the antagonist of Duquesne, the equal, and by some thought even the superior, of Tourville, whose name has always stood far above all others in the French navy of that day.

The Spanish navy throughout seems to have behaved badly, certainly inefficiently; and early in 1675 the French were safely established in the city.

During the year their naval power in the Mediterranean was much increased, and Spain, unable to defend the island herself, applied to the United Provinces for a fleet, the expenses of which she would bear.

The Provinces, "fatigued by the war, involved in debt, suffering cruelly in their commerce, exhausted by the necessity of paying the emperor and all the German princes, could no longer fit out the enormous fleets which they had once opposed to France and England."
